Well, you're right, one option may be to wait for it and then order a case...

However, there is still that distance of 650 km between it and me, and the person that brings it to me will travel by train. As I don't want to take the risks a gigbag would cause, I have to order a case and send it to Berlin. So thanks for the tip, but patience is no option for me.

Build one, Hans!! I'm about to set-to and build one for my U-60 and it's not a terribly difficult build at all! 9mm ply, some glue, screws and aluminium corners and a hinge or two and bingo! then get your local foam store cut you a piece of foam or polystyrene for the body shape and you're laughing!
